ok guys heres a long story short.
got my car back from the tuners a week ago, was runing superbly, wasnt missing a beat. nyway yesterday im taking the car out of the driveway, i give it a bit of a hit, and once d revs reached around 4000+ it made dis loud screeching noise. so i backed off and geared up. tried it in second gear and same thing. anyway granny shifted for a few minutes tried giving it a hit again, and the noise was gone for the rest of the trip. parked the car at the shops for bout 45mins, and when i got back in it and drove off, it did d same problem for d first 5 mins of driving den disapeared.
i thought maybe its d turbo, however, no loss of oil or any smoke. also if it was the turbo, i assumed d noise would be constant, not leave after 5 mins of driving. anyone got anyyyy ideas what it could be???
